new A1 fly solenoid problems

Hello, I just got my brand new angel a1 fly joy edition and the marker is just perfect I love it all ready even I didn't shoot a single paintball with it cause the freaking solenoid gets stuck in the shooting / open position when I connect air and make one shot .
I did open the back of the gun reset the noid( push the piston a small step back to the el magnet ) then connect air and make one shot and the air start leaking down the barrel until I repeat the same reset again.

Don't know what to do else, does anyone have an idea what I can do to fix that?

-New Fresh battery (duracell or energizer to be safe, no no-name brands)

-Make sure the breach seal is glued down flat. If it is lifted it will lift and lock the breach block causing the bolt to stay forward and dump air. Lift off the seal and pick off all the old adhesive and reglue with a drop of superglue.

-Make sure the dwell is 6.5ms.

-Make sure the detents are fresh and not ripped.

-Make sure the bolt pin did not back out or is loose in the bolt. Take the bolt out and tap the bottom of the metal pin on a hard/smooth surface to ensure it is seated all the way down.

Be very careful of the solenoid. The spool is very delicate and those small spool seals can get damaged. Make sure the solenoid goes back together correctly with a little grease on the spool and the gasket is on correctly and lightly greased.

OK, thanks for a quick response:-)
Have done that, fixed the breach seal and changed the battery to a new energizer , dwell is by 6,5, still the same problem.
And like I sad the gun is brand new , I have only changed to a mojo board

Open up the volume chamber plug in the front and ensure both magnets (1 on the plug and 1 on the cupseal) are intact and secure. Then make sure the white delrin cupseal ring is attached to the stem securely as well.

Check your pressures as well. 200psi on the reg and 55psi on the lpr are safe to start out with.

If everything is fine, last thing would be to go back to the solenoid, something is not right. Seems like the spool is sticking in the open position. Push the spool out very cautiously, wipe with soft napkin and lightly re-grease. Clean out the solenoid block where the spool slides into, making sure no debris are inside. Recheck everything carefully making sure the block was put back together right.

If this only happens when you first air up, try simply pushing the bolt back with a squeegee and take a couple dryfires and oftentimes it will reset. That is a common issue and really nothing to be concerned about.

If the problem persists, check your solenoid for a tell-tale dent in the top of the body. If it's there, odds are good someone overtightened the solenoid clamp screw at some point in its life and crushed the body, causing the piston to stick.

You won't necessarily get a leak from the 'noid even if you've crushed the body. Particularly if you forget the spreader that goes on top, you can put a nice solid dent in it without actually cracking it and it'll just cause the piston to stick. Just one thing to check as long as you've got the solenoid cover open - definitely check the gasket and those other things as well.

I had this problem when I put the Booster Bolt 2 on my Angel. Kept getting bolt stick and other minor problems. I went back to stock and everything performed well. Sometimes the tolerances from A1 to A1 are different and one will perform differently from the other.

It's kind of hard to tell from the pic how severe/deep the dent is. Pushing the piston through the body manually will tell you if it's sticking though. If so, unfortunately there's no fix besides a new solenoid.

There is a potential fix, but it will take a custom made tool. The tool is simple but needs to be made precisely. While I have not used this technique on this part, I have used it on other items that require a dent be pushed out of a cylinder.

The tool is basically a tight fitting rod with a flat ground on one side. You then insert the rod into the cylinder with the flat facing the dent and rotate the rod. You may need to place the part in a vice and use a wrench on the rod to turn the dent out. This will iron out the dent though you want the rod to be made of a harder metal/composition than the cylinder or you will simply deform the rod.

Here is a rough MS Paint drawing of the tool:

I'm not sure if having a custom tool made is less expensive than a replacement part or if the part can handle the dent removal process but it is a way that works in other applications. If you have access to a lathe and a grinder you can make the tool at home for very little cost. I would make the tool as close to a perfect fit (ignoring the dent) as you can get. It also doesn't hurt to smooth the transition from ground down area to full diameter of the rod. It also helps if the tip of the rod is chamfered to allow easier insertion into the part. I would have included them in the drawing but my MS paint skills are minimal.

Today I finally had some time to make that tool was a bit tricky to find something in the right size but I did work :-)
The gun shoots awesome , did shoot just a mag full of paint and run out of air , will test it more tomorrow and make the pics from the tool , maybe it helps someone here.
